Python 3.10.x its PyIter_Send() will return PYGEN_ERROR if the
generator returned (as opposed to yielding) if the result returned
is Py_None and no argument was given to PyIter_Send(). Which is counter
intuitive since it seems it should give us a PYGEN_RETURN as per its
documentation.
It also no longer sets PyExc_StopIteration in this case so we cannot depend
on that anymore to figure out if a coroutine has finished.
This caused Kore to respond with a 500 immediately after coroutines
ran to completion as it was looking for the PyExc_StopIteration exception.
Fix this by simply doing another check if an exception happened before
we enter the code path where Kore would spew the 500.
The cmsghdr contains a length (cmsg_len) which indicates the length
of the data in combination with the cmsghdr length itself.
Remove the length of the cmsghdr before passing it back up to callers
so they don't need to bother with it.
This also fixes a mistake where we ended up copying extra data
from the ancdata buffer that was unintended.
When this code was moved from src/connection.c into src/tls_openssl.c
a return wouldn't break us out from kore_connection_handle() as
previously expected.
This ment that Kore would move the connection into established state
immediately even if SSL_accept() needed to read more.
This broke TLS client authentication as Kore its belts and suspenders
kept throwing a 403 due to the code not properly obtaining the client
certificate when expected.
The whole while (cnt-- >= 0) idiom is busted since cnt started
at 0 and if the first call to PyUnicode_FromStringAndSize() fails
then we're attempting to access -1.
use it in places explicit_bzero() used to be called.
The kore_mem_zero() is a best effort to try and let the compiler
not optimize the code away. Highly platform dependent.
This work moves all TLS / crypto related code into a tls_openssl.c
file and adds a tls_none.c which contains just stubs.
Allows compilation of Kore with TLS_BACKEND=none to remove building
against OpenSSL.
Also adds code for SHA1/SHA2 taken from openssh-portable so we don't
depend on those being present anymore in libcrypto.
It wasn't possible for the parent process to send messages
directly via kore_msg_send() to other worker processes.
This is now rectified to from the parent process one can call
kore_msg_send() with a worker destination and it'll work.
Wait for any process in our process group only instead of WAIT_ANY.
This allows the parent process to start subprocesses that end up
in different process groups which are handled in user code instead
completely (using signalfd for example).
Inside of the new route handlers the "authenticate" keyword can
be specified to let the route authenticate via a previously
configured authentication block.
The ability to do this went missing in a previous commit that overhauled
the routing structure of the configuration.
Just noticed the 5 seconds wasn't enough when renewing all
certificates in my own setup (i have about 30 ACME domains via Kore).
Bumped it to 30 seconds instead.
If no accesslogs are enabled, the parent has no need for
the vacuum timer to be activated.
This way the parent blocks in epoll_wait() instead of waking up
for no reason when there are no accesslogs enabled.
This commit adds improved hooks for Python and a new signal delivery hook.
For the Python API kore_worker_configure() and kore_worker_teardown() had
to be implemented before this commit. Now one can create a workerstart
and workerend method in their koreapp as those will be called when
they exist.
The new signal hook is either kore_worker_signal() or koreapp.signal.
This new hook is called after the worker event code handles the received
signal itself first.
With this commit there is also a new kore_signal_trap() API call allowing
you to more easily trap new signals. This API also also exported to the
Python part of the code under kore.sigtrap()
